Filter fusion

Abstract

Filter Fusion is a new compiler optimization that eliminates the overhead of a modular design of independent filters, and automates the integration of arbitrary, independently designed filters. The Filter Fusion compiler (FCC) composes of filters and produces code that is as efficient as hand-integrated code. While Filter Fusion is well suited for systems software applications, no assumptions about its problem domain are made. FCC places few restrictions on the filters it integrates. It also handles arbitrary control flow and data manipulations within each filter.
